PRESENTATION OUTLINE

PLATE TECTONICS

PLATE TECTONICS IS THE THEORY THAT EARTH'S SHELL IS DIVIDED INTO SEVERAL PLATES

CONVECTION CURRENTS

A CURRENT IN A FLUID THAT RESULTS FROM DISPLACEMENT OF HEAT

SLAB PULL

SLAB PULL IS THE PORTION OF MOTION OF A TECTONIC PLATE THAT CAUSES SUBDUCTION

RIDGE PUSH

IS THE PUSHING OF NEW ROCK BEING FORMED IN BETWEEN TWO PLATES MAKING ROOM AND PUSHING THE PLATES APART

DIVERGENT PLATE BOUNDARY

IS A FEATURE THAT EXISTS BETWEEN TWO TECTONIC PLATES THAT ARE MOVING AWAY FROM EACH OTHER.

LANDFORM RESULTING FROM DIVERGENT PLATE BOUNDARY (LAND)

A RIFT VALLEY IS CREATED AT A DIVERGENT PLATE BIUNDARY : EAST AFRICAN RIFT

LANDFORMS RESULTING FROM DIVERGENT PLATE BOUNDARY (SEA)

MID OCEAN RIDGE: JUAN DE FUCA RIDGE

CONVERGENT PLATE BOUNDARY

ONE PLATE SUBDUCTS UNDERNEATH ANOTHER PLATE

VOLCANO ARC AND TRENCH

RESULT FROM OCEANIC CONTINENTAL CONVERGENCE

ISLAND ARC

IS THE RESULT OF OCEANIC VS OCEANIC CONVERGENCE

MOUNTAIN RANGE

RESULTS FROM CONTINENTAL VS CONTINENTAL CONVERGENT PLATES-HIMALAYAN MOUNTAINS

SUBDUCTION ZONE

THE ZONE WHERE EXCESS MATERIAL IS SCRAPED OFF ONTO THE SHORE AND WHERE ONE PLATE GOES UNDER ANOTHER

DEEP OCEAN TRENCH
